Neuroanatomy Review Part 2- Cranial Nerves

Front

A categorization that refers to nerves that send motor commands from the CNS to muscles or glands is __________.

Back

Efferent nerves (also known as motor nerves) transmit signals from the central nervous system (CNS) to effectors such as muscles and glands.

Front

Which branch of the Vagus (CN X) supplies the larynx?

Back

Recurrent laryngeal nerve - This nerve innervates the muscles of the larynx, playing a crucial role in voice production.

Front

A sensory nerve innervates the diaphragm. How would you characterize it?

Back

GVA (General Visceral Afferent) - This type of nerve carries sensory information from the diaphragm to the CNS.

Front

Nerves that are located in the brainstem and are responsible for transmitting signals from the brain to the muscle and back are called:

Back

Lower Motor Neurons (LMN) - These neurons directly innervate skeletal muscles and are essential for voluntary movement.

Front

A categorization that refers to pain, touch, and proprioception is __________.

Back

General somatic afferent (GSA) - These nerves convey sensory information regarding pain, touch, and body position.

Front

What is the function of the Olfactory nerve (CN I)?

Back

The Olfactory nerve is responsible for the sense of smell, transmitting sensory information from the nasal cavity to the brain.

Front

What is the primary function of the Optic nerve (CN II)?

Back

The Optic nerve is responsible for vision, carrying visual information from the retina to the brain.

Front

Which cranial nerve is responsible for eye movement and pupil constriction?

Back

Oculomotor nerve (CN III) - It controls most of the eye's movements and regulates the size of the pupil.

Front

What is the role of the Trigeminal nerve (CN V)?

Back

The Trigeminal nerve is responsible for sensation in the face and motor functions such as biting and chewing.

Front

Which cranial nerve is involved in hearing and balance?

Back

Vestibulocochlear nerve (CN VIII) - It transmits sound and equilibrium information from the inner ear to the brain.
